Schwalbe Ultremo: expensive ($65); ultra-light; surgically precise handling; extremely low rolling resistance; reasonable flat protection; cut easily.
Continental 4 Seasons: expensive ($68); good handling; low rolling resistance; excellent flat and cut resistance; very grippy.
Continental Top Contact 28mm: less expensive ($50 with wire bead); excellent handling; very low rolling resistance; the best flat and cut resistance short of an industrial tire (one year no-flat guarantee); very grippy; easy to mount and unmount; tread design does not throw up rooster tail in rain (no fender required below 20 mph); my current tire.
